block supplicant scan when there is an active Miracast connection.

[Arik - added a delayed scan instead of a cancel, since cancelling the
scan will screw up android "open network detection". We always start a
new scan from the last scan results. The way the p2p- interface is
checked here is very ugly - relying on the group interface to be added
last and at the beginning of the list.]
Add 60msec delay before sending EAPOL4 frame

Add 60msec delay before sending EAPOL4 frame, since Flames
sink is not able to send the ACK for EAPOL4 if we send with out
any delay
Do not send command "SETMIRACAST" to the driver

SETMIRACAST command is not implemented in the driver,
so do not send the command to the driver. Currently,
driver does not take any action if miracast mode is active.
Android: wpa_supplicant_template: define config methods
